QUESTION
EDIT: Java/FX Version: 13.0.2
IDE: Eclipse 4.13.0
Tracker and changePerFrame values are declared as private double variables on the class level.
Goal: Create a timeline that makes a short animation sequence using a Canvas and Image. Image will start with a X/Y location off screen, and an increased Size. The image will then shrink and move into view, creating a sort of zoom-out?/Shrink? effect.
Issues: When creating a new KeyFrame inside the loop, the correct values are not being passed. The values when printed inside the loop using println, are correct, but the values being passed in '(evt -> swordAnimation(xTracker, yTracker, wTracker, hTracker))' are always the same incorrect value. Can anyways explain why this happens?
...ANSWER
Answered 2019-Oct-28 at 17:01You're storing the values in fields. Those field values are evaluated at the time the lambda expression is invoked. This is after the completion of the loop and therefore every frame sees the final values.
Create final
local variables storing the intermediate values and use them in the lambda instead:
